what is the weight of a cubic meter of cork? could you lift it? (use 400 kg/m^3 for the density of cork.)

Answers

Answer 1

To lift this weight, you would need a force greater than or equal to 3,920 N (assuming you are lifting it vertically).

weight = [tex]1 m^3 \times 400 kg/m^3 \times9.8 m/s^2[/tex]

weight = 3,920 N

Force is a physical quantity that describes the interaction between objects or systems. The SI unit of force is the Newton (N), which is defined as the amount of force required to accelerate a one kilogram mass at a rate of one meter per second squared.

Force is also responsible for deformations in solid objects, such as stretching or compressing a spring. Nuclear forces are responsible for the interactions between subatomic particles, and frictional forces are the forces that resist motion when two surfaces come into contact. Gravitational force is the force that pulls objects towards each other due to their masses. Electromagnetic force is responsible for the interactions between charged particles, such as in electricity or magnetism.

a student is 2.50m away from a convex lens while her image is 1.80m from the lens, what is the focal length?

Answers

To find the focal length of a convex lens, we can use the formula:
1/f = 1/di + 1/do

Where f is the focal length, di is the distance of the image from the lens, and do is the distance of the object from the lens.

We are given that the student is 2.50m away from the lens, so do = 2.50m. We are also given that the image is 1.80m from the lens, so di = 1.80m.

Plugging these values into the formula, we get:
1/f = 1/1.80 + 1/2.50

Simplifying this equation, we get:
1/f = 0.5556

Multiplying both sides by f, we get:
f = 1.80 / 0.5556

Solving for f, we get:
f ≈ 3.24 meters

Therefore, the focal length of the convex lens is approximately 3.24 meters.

A convex lens is 1.80 meters from a student who is 2.50 meters distant, and its focal length is 1.04 meters.

To solve this problem, we can use the lens equation:

1/f = 1/do + 1/di

where f is the focal length of the lens, do is the object distance (distance of the object from the lens), and di is the image distance (distance of the image from the lens).

In this problem, the object distance is do = 2.50 m and the image distance is di = 1.80 m. We can plug these values into the lens equation and solve for the focal length:

1/f = 1/do + 1/di

1/f = 1/2.50 + 1/1.80

1/f = 0.4 + 0.56

1/f = 0.96

f = 1/0.96

f ≈ 1.04 meters

Therefore, the focal length of the convex lens is approximately 1.04 meters.

A mass of 25. 0 kg is acted upon by two forces: is 15. 0 n due east and is 10. 0 n and due north. The acceleration of the mass is

Answers

the acceleration of the mass is 0.7212 m/s^2.

To find the acceleration of the mass, we need to first determine the net force acting on it. We can do this by using vector addition to add the two forces together.

Using the Pythagorean theorem, we can find the magnitude of the diagonal force:

sqrt[[tex](15N)^{2}[/tex] + [tex](10N)^{2}[/tex]] = sqrt[225 + 100] = sqrt(325) = 18.03 N

The direction of this force can be found using the inverse tangent function:

theta =[tex]tan^{-1}(10.0N/15.0N)[/tex] = 33.69 degrees north of east

We can now use vector addition to find the net force on the mass:

F_net = sqrt[[tex](15N)^{2}[/tex] + [tex](10N)^{2}[/tex]] = 18.03 N, at an angle of 33.69 degrees north of east

To find the acceleration of the mass, we can use Newton's second law, which states that the net force acting on an object is equal to its mass times its acceleration:

F_net = ma

Solving for the acceleration, we get:

a = F_net / m = 18.03 N / 25.0 kg = 0.7212 m/s^2

Therefore, the acceleration of the mass is 0.7212 m/s^2.

consider the picture above of mars's orbit around the sun. which spot shows where mars will be when we see it in retrograde motion on earth?

Answers

When retrograde motion occurs and how it is related to Mars's orbit around the Sun:

Retrograde motion occurs when a planet appears to move backward in the sky from Earth's perspective. In the case of Mars, this happens when Earth overtakes Mars in their respective orbits around the Sun.

To understand when Mars will be in retrograde motion, consider these steps:

1. Picture both Mars and Earth orbiting the Sun, with Mars having a larger, slower orbit due to its greater distance from the Sun.
2. As Earth moves faster in its orbit, it eventually catches up to and passes Mars.
3. During this time, the relative positions of Earth, Mars, and the Sun create the illusion of Mars moving backward in the sky, as seen from Earth.

So, when trying to identify the spot where Mars will be in retrograde motion, look for the point in its orbit where Earth is passing Mars, creating the optical illusion of Mars moving backward in the sky.
